00:01We'd now like to talk about building applications using ArcGIS Online.

00:06You can build web, device, and desktop applications.

00:09And you can use web maps to organize and model the information that's at the core of these applications.

00:16The applications can add additional behavior onto that core content.

00:21You can also connect to portals and work with users, groups, and items that are contained in these portals.

00:27And you do this using the new ArcGIS Portal REST API that we'll be talking about on Thursday.

00:34As an organizational developer, you can build custom applications for the end users within your organization.

00:41As an independent developer, you can use ArcGIS Online as a powerful geospatial platform that powers your apps.

00:50This slide shows the architecture of an organizational subscription from the perspective of the users of that subscription.

00:59The organizational subscription represents your cloud GIS instance.

01:04It includes a portal as well as hosted services.

01:08The portal is the repository of your users, the groups, and the items.

01:13The hosted services are the services that you publish using uploaded data.

01:19You can also connect your enterprise servers to this organizational subscription like we've shown you earlier...

01:27...and you can register the services within your portal.

01:31The ArcGIS Online website provides the web user experience to the whole assemblage and then, of course...

01:37...you have your own applications that access that.

01:40And those applications are working with the portal services, and they're working with the geoservices...

01:46...that are either inside the hosted system or in the enterprise system.

01:50So that's how you build applications with Online.

01:55ArcGIS Online has a simple information model, and you see it here, a portal containing users, items, groups.

02:04Items are classified into web maps, layers, applications, tools, and data files.

02:13Layers correspond to standard web services, the geoservices that come from your server or hosted services...

02:20...including feature services, dynamic map services, tiles, image services, KML...

02:28...and data files include the files that you upload to create these services from...

02:33...including CSV text files, shapefiles, packages, and so forth.

02:42So in summary, application development is done using the ArcGIS web APIs if you're doing browser-based development.

02:49We have APIs for JavaScript, for Silverlight, and Flex.

02:53You use the ArcGIS Runtime APIs if you're building apps for devices, iOS, Android, Windows Phone.

03:00The core app content can be modeled as a web map that you first author and then you bring into your app.

03:06There's a variety of configurable application templates for JavaScript developers...

03:11...and then there are application builders for Silverlight and Flex developers.

03:16So let's look at building some applications with Online.

03:19And Jeremy's going to help us do that.

03:20Alright. Thank you, Sud.

03:24So web maps, as you know, are a very powerful concept.

03:27I'm going to take you through that and how you can use it to build hosted applications.

03:31So started with a simple map.

03:33Now this map, you know, like I said, we picked the basemap, and then we decide what layers we want to bring in.

03:39USGS has a great resource, of course, for earthquakes.

03:43This data is updated all the time.

03:45In this case, magnitude 5 CSV file is always there, updated every few minutes.

03:51So I can copy this URL and go ahead and add it to the map.

03:55Many different ways to add layers to this map.

03:57I can search for existing layers in ArcGIS Online.

04:00I can target directly my own ArcGIS Server.

04:03I can use my hosted online services.

04:05I can upload a CSV from a file or a shapefile.

04:09I can add a layer from the web and specifically...explicitly target my own GIS server, WMS, KML...

04:15...or in this case, the CSV file.

04:18So it's a very open platform for building these web applications.

04:24There we go. Now the points are added to the map.

04:27And if I touch them, all of those attribute fields in that spreadsheet now show up as name value pairs in this pop-up.

04:32But, of course, you don't want to stop there and take the defaults.

04:35You want to turn this raw data into useful information.

04:39In the interests of time, I've already done this, and I'll just remove this. Turn this on.

04:45Now in this case, I've changed the symbology of that feature...of that layer, excuse me.

04:50I've changed the pop-up, pointing out more information, creating URLs on the fly...

04:56...using all of those attributes, the template in components.

05:00So if I look at the configuration, got a custom configuration.

05:07I'm dropping in the attribute field date time and the attribute field magnitude in here and I've bolded it...

05:12...and I've generated this hyperlink that pulls two other attributes along with the base URL.

05:20I can also go back and change the symbols.

05:23So in this case, I've symbolized by size, or excuse me, by size with the attribute field magnitude.

05:29And then I have a very nice little map.

05:33Now, I can take this map and, of course, I can embed it in my website.

05:43Now this map is real. I could open it up on...on many of the devices.

05:47This is a hugely popular component of ArcGIS Online.

05:50But I'm going to show you a slightly different angle.

05:52I'm going to take this map and pass it to a web application.

05:55So as Sud said, we have many different configurable web applications.

05:59I could drop it into this web application that focuses on the legend...

06:03...and then all that...all the content of that web map in the configuration just comes along with it.

06:11Or, I can publish...publish my...I can take that web map and publish it into this web application.

06:16This is a configurable hosted web application.

06:26It's going to be saved online within the ArcGIS Online system as a web application.

06:32I can go to that item now as the owner, and because it's configurable, I can go ahead and configure it.

06:40So each one of these templates can have a different set of configuration components.

06:45So in this case, this template lets me change the color scheme.

06:48I can change the logo. It's probably this.

06:57I could configure and turn off other aspects.

07:00We've even integrated the 10.1 print service.

07:04Now I'll save this.

07:06Now notice I've got my own URL.

07:07This application's hosted for me inside of arcgis.com.

07:11And when I open that up, it's going to be completely configured how I'd authored it.

07:15This is a very powerful concept and also in the context of your organization.

07:20You as a developer...if I was a developer for the City of Washington, DC...

07:24...I could build a set of applications that are meant to serve not just the people and the public, but the...but people within my organization.

07:32They can be highly focused applications.

07:34You know, all they take in is the web map, and they can be configurable.

07:37So I think you guys are going to start building a lot of these configurable applications...

07:41...in the context of your organizational subscription.
